Application filed November 18, 192 2. Seria1'No. 601,725.

To all whomit may concern:

Be it known that I, LE J. GRUBMAN, a citizen of they United States, and a resident of the borough of Bronx, county of Bronx,

5 city and State of New York, have invented certain new and useful Improvements in Sound-Producing Devices for Dolls, Etc, of which .the following is a specification sufiicient to enable those conversant with the art to which the invention appertains plication Serial No-.-- 542,884, filed Marchllth, 1922. As in that case, the object of my present invention is the production of asimple, substantial, compact, self-cont'a'ined device of. the character designated having no extraneous parts,'and which is gravity-automatic in action in the sense that the use of springs'is obviated, and in that no external pressure is necessary for 0 sound production,the objects of my present improvements as related to the structure disclosed in the aforesaid application Serial No. 542,884t, being the perfection and amplification of sound production, and certain structural advantages incidental to standardization j of manufacture. The impor tantfeature of my present disclosure resides in the provision of simple, effective and easily applied means for fixedly securing certain parts of the mechanism enclosed -within the outer shell or casing to' the op 'posite ends of the shell wall whereby the use ofglue or other adhesive ma be dispensed with. In the. present em diment of my invention .I propose to provide the ,niarg'inal portion of themetallic end plate t-losing one end of-the casing .with suitably formed means for clamping engagement or partition whichis fixed at its edge to plates for theshell or casing;

-- upon the end of the bellows wall and over the casingwall by- 1neans on the other end" plate of the'casing similar to that securing the bellows wall in place and which provi esa -soun'drece'iv'ing chamber of com paratively restricted and. definite dimend sions so that the sound will finally issue from the device in substantially constant volume. I With the above and other objects in view, the invention consists in v the improved combination, arrangement and construction of the several elements as will be hereinafter more particularly described, illustrated in the accompanying drawings and subsequently incorporated in the subjoined claims;

In the accompanying drawin emplify a preferred and practical embodiment of the essential features of my invention, although I doxnot limit myself to the I ex-.

identical form and construction of parts 7 shown, since modifications in. minor details, and equivalent mechanical expedlents may departing from the spirit and invention in this respect.

As heretofore, the operative parts of my sound-producing device are enclosed in a rigid casing, consisting, in the preferred construction as shown by way of exemplification in the accompanying drawings, of a' cylindrical shell 0, closed at one of its ends by the disc 0', and at its other end by an apertured plate or disc 0 The external configuration of the box or casing is of secondary consideration, its function being simply to isolate and and to afford ed external dimensions, in such manner as to render the device considered in a unitary sense, self contained, and without protuberant parts. In this connection, it is obvious that the container or casing 0, c, 0 might be other than cylindrical in shape with substantially like results, although the form of casing shown is preferable for simplicity, compactness and cheapness of structure.

The head plate c of the casing is formed with one or more apertures 0 for communication with the atmosphere. However, it will be apparent that communication w1th the atmosphere might be provided for through the upper portion of the cylindrical shell 0, adjacent to the head plate a, or elsewhere, if found expedient, with like result, in that provision is thus made for inlet and outlet of air and of sound vibrations.

The sound emission pipe a, which also functions as a guide and lateral support for the free or movable head b, of the bellows B, is likewise preferably, but not necessarily of cylindrical form, and positioned centrally as related to the casing and bellows, and is fixedl secured to and between the casing end p ates c, and 0 as shown more particularly in Figs. 5, 6, and 8, of the-drawings. Hence, it may consist of a. tube a, held in plate at one extremity by a depression 0", in the plate 0, and at the other extremit .by the edge of the central opening 0 i the plate 0 fitting in an annular groove a, (Figs. 8 and 15) formed in the'peripheral surface of said wind pipe a, adjacent to one end thereof, the extreine outer edge of the tube being eaned or bent over the outer surface of said plate 0 thereby locking the wind pipe in place. This construction is shown in Figs. 5, 6, 8, and 15, of. the drawings, Fig. 15, illustrating the method of attachment of the tube end to the plate 0 rotect said operative parts,

pipe a, and the plate '0 'The other extremityof the pipe a,-is closed and sealed by the aforesaid depression 0", of the disc 0, within which depression 0", the lower end of the pipe fits, making a tight joint therewith. Within the latter. end of the pipe a, is positioned a reed 1', or equivalentsound producing element supported in the plug 1*, the side of the tube adjacent thereto, and between it and the inner side of the disc 0', being formed with one or more apertures a", through which communication is established between the interior of the bellows B, and said pipe a, so as to afford adequate means for the admission of air to, and its expulsion from, the-interior of the bellows B, in the operation thereof.

Air is admitted to or expelled from, the pipe or tube a, through the medium of the apertures ai, a", which communicate with the sound receiving chamber a between the apertured plate 0 and the resonator or sound intensifying partition P, which latter is rigidly positioned within the casing and as related to said plate 0 as shown more particularly in Figs. 5, 6 and 8, of the draw mgs. I

Said resonance partition P which controls the final emission of sound through the apertures 0 is preferably of concave form on the side thereof opposed to the apertured plate 0 of the casing as shown in the drawings, so as to concentrate and align the sound waves or vibrations emanating from the .wind chest in a manner essentially parabolic, although I do not limit myself in this respect, since the main function of said partition P, is; to definitely limit the area of the sound receiving chamber a of the device and separate it from the rest of the in-.

invention in this respect consists in inter posing between the apertured plate 0 of the casing, and the movable head I), of the bellows B, a fixed partition P, which prescribes the area of sound deflection and confines it to the space adjacent to the emission end of the pipe or tube a, and between aperture a and the aforesaid apertured plate 0, as shown in Figs. 5, 6 and 8, of the drawings.

The said resonance partition P, is formed with a central opening 70, for the accommodation of the pipe or tube a, and it maybe fixedly attached to'the casing in any suitable manner, a preferred method being shown in Figs. 5, 6 and 8, of the drawings, in which said partition P, of concavo-concircumferential edge of which is formed with a channel bead clinched a ainst the outer surface of said casing shell 0, with the lower edge of said flexible member 12", interposed between said plate and the shell wall, as clearly indicated in said. Figs. 5, 6, and 8, of the drawings.

The other end edge of the flexible member b", of the bellows is attached to a circumferential flange 6 on the movable bellows head I), by means of a clampin ring-b this method of attachment being inexpensive and effective, and the jointure being attained thereby in a simple manner. -Thus it will be noted that the ring 6 positively clamps the end edge portion of the flexible bellows 0 wall against circumferential angularly related surfaces of the bellows head, and that one of these surfaces acts to positively limit the axial movement of this ring relative to the head to its effective clamping position upon the end edge of the bellows. By thus clamping the flexible bellows wall against the two angularly related surfaces of the head, greater security is obtained with less liability of the end of the bellows wall becoming detached from said head and also a more perfect .air tight seal is assured. Should one of said surfaces of the movable bellows head contain imperfections, the escape of air would nevertheless be prevented by the tight frictional clamping contact of' the bellows wall with the other surface of said head. Also, I have found that the use of such a frictional clamping connection between the flexible bellows wall and the blage of the parts over that incident to the use of glue or other adhesiyes and also reduces manual labor to a minimum.

The A bellows head b, is provided with sound control means having valve ports b b and functions substantially asset forth in my concurrent application Serial No.

5 and secured thereto by-the platec which constitutes a common closure for this end of the casing and the bellows chamber. However, it is not essential in practice that the form of this closure plate shown in the drawings, shall be strictly adhered to, though I prefer to provide this plate, whatever its form may be, with a part constituting a stop by reason of its coaction with the end edge of the casin wall to prevent the possibility of said pfiite being forced into the casing.

I have found that the turning of the end edges of the flexible bellows wall in reverse directions over the edge of the air expelling head and the casing end respectively is of material advantage in facilitating the easy and rapid assemblage of the parts of the bellows structure in connection with the cas ing wherein this bellows is housed or enclosed.

It will also be understood that the particular form in which the partition P is illustrated in the accompanying drawings is not essential to the proper operation of the device, and this partition might be otherwise constructed and mounted within the casing end, the essential consideration being that the partition or its equivalent Thus a more realistic simulation of the spoken pronunciation of "word syllables is produced than would be the case, if such partition or its equivalent was omitted, and the area of the casing chamber into which the sound is emitted through the aperture a constantly increased during the air expelling movement of the bellows head. movable head greatly expedites the assem- From the foregoing it will be manifest that I have produced a device of this kind in which notwithstanding the very simple Ill and compact arrangement of the parts of the sound producing mechanism within a housing or casing. of relatively small dimensions, there will be produced in a posi-' tive manner a very realistic simulation of the desired word syllables. Therefore, since it is manifest that the essential characteristics of my present improvement might be: exemplified in numerous other alternative structures, it is to be understood that I reserve the privilege of adopting all such legitimate changes in the form, proportion and relative arrangement of the several parts asmay be fairly embodied within the spirit and scope of the invention asclaimed.
